How you sleep could help you lose or gain weight, according to a pretty cool study. Welcome back to 30 studies to change your life. Sleep Week continued. We've been talking about some cool ways to improve your sleep, but here's one reason why it matters. You know, in case the feeling of being tired isn't bad enough. Weirdo. Researchers took healthy men and had them sleep for either eight hours a night or four and a half hours a night for four consecutive nights, all while eating a carefully planned healthy diet. After that fourth night, they were then given an all-you-can-eat lunch buffet, and an unlimited snack bar in between. And they were measuring their hunger and satiety hormones throughout the whole process. They found that Grelin, the main hormone that sends hunger signals to your body, was consistently elevated when they were sleep deprived. And while this didn't really impact how much they ate for lunch or dinner, when sleep deprived, they ended up snacking way more, especially carbohydrates, leading to an average consumption of an extra 328 calories for the whole day. Do that for a whole year and you'll end up 34 pounds heavier. And it's not just Grelin. Another study found that sleep deprivation led to an increased activation of a brain reaching called anterior synchrobat, anterior cingulate cortex, which is in charge of your reward response when anticipating food, leading people to rate foods as looking more appetizing. And if you're a fellow science nerd who wants to learn more about all the ways that you can improve your sleep, hit that follow button and come along as we continue our scientific deep dive. If you have a specific issue you want me to cover, let me know down below.
